As otherwise they would fail during the self-test which is required during registration. In the past we have used subsystem initialisation ordering to guarantee this. The number of such precedence levels are limited and they may cause ripple effects in other subsystems. This patch solves this problem by delaying all self-tests during boot-up for built-in algorithms. They will be tested either when something else in the kernel requests for them, or when we have finished registering all built-in algorithms, whichever comes earlier.
